WASHING- MACHINE.

SPEGIFIGATION forming part of Letters Patent N 0. 569,619, dated October20, 1896.

Application filed July 8, 1893. Serial No. 479,986. (No model.)

To all whom it may concern.-

Be it known that I, CONRAD DIETZ, a citizen of the United States,residing at (lovington, Kenton county, State of Kentucky, have inventedcertain new and useful Improvements in lVashing-llachines, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

My invention relates to that class of washin g-machines having asemicylindrical vibratory receptacle for the clothes and acorrespondingly-shaped vibratory dasher for rubbing and turning saidclothes, my invention consisting of the means hereinafter set forth forvibrating said receptacle and'dasher from a single crank-shaft.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through a washing-machine embodying my invention; and Fig. 2 isa top view of same, partially broken away. Fig. 3 is a sectional viewillustrating a portion of the machine with its lid and dasher elevated,showing the manner in which the connecting-rod is attached to or removedfrom the clothes-receptacle. Fig. i is a view illustrative of thepreferred form of hinge for li1niting the backward movement of the coverwhen elevated. Fig. 5 is a vertical section on dotted line 5 5 of Fig.1, looking toward the left hand in said view. Figs. 6 and 7 are enlargedperspective views of the preferred form of device for making theconnections between the clothes-receptacle and the pitman-bar.

In the drawings, A represents the outer casing or tub, and B theclothes-receptacle vibratorially connected thereto, the inner face ofsaid receptacle having ribs 1) in the usual manner.

C represents the cover, which is hinged to the tub, and preferably bymeans of the stophinge shown in Fig. l, one part of said hinge having ahook a, the other having a lateral stud a said hook and stud at eachside the machine being adapted to engage with each other to limit thebackward movement of the lid. To each inner side face of the cover isattached the bracket-bearing biwithin which the journals (Z of dasher Dengage, as more clearly shown in Fig. 5, the outer face of said dasherbeing ribbed in the usual manner.

The bracket-bearings b are each provided with an elongated groove closedat the top, Within which the journals (Z of the dasher rest. Thesejournals normally rest on the bottoms of the grooves, but are free toyield upwardly a limited distance, the closed top of the groovesabsolutely preventing the clothes from forcing the top of the rubber upagainst the under side of the lid or cover a, which would interfere withthe movements of the rubber. The closed grooves also hold the rubberagainst displacement when the cover is thrown to a vertical or openposition. To the cross-piece (Z of the dasher is attached the arm (1",to the free end of which is pivoted one end of the pitman E, theopposite end of the latter being rotatably connected to the crank e ofshaft F, which latter is provided with a suitable drive-wheel G. Therotation of said drive-wheel, through the medium of shaft F, crank e,pitman E, arm (Z and crosspicce 61 will cause said dasher to vibrate inopposite directions.

H represents the connecting-rod, which is pivoted at top to the underface of pitman E, the lower end of said rod being pivotally connected tothe top edge of one end of receptacle B. In Figs. 6 and 7 I haveillustrated the device for pivotally connecting the rod II to saidpitman and to the clothes-receptacle, which consists of the plate Jhaving a stud j and a horn or shield j projecting down beneath saidstud, as shown, said plate being attached to the under face of pitman E,as shown in Figs. 1 and 3. The plate K is provided with a similar stud7t" and horn W, said plate being attached to the top cross-piece Z1 ofreceptacle B, as shown.

The bar or rod H is first pivoted on stud j by swinging said rod outabout parallel with plate J, at which time it is readily placed on saidstud and swings down at the rear of horn 3' The lower end of said rod ispivoted on the lower stud it by tilting the receptacle upward, as shownin Fig. 3, out of line with the end of horn If, at which time said rodis readily placed upon or removed from said stud.

WVhen the parts are in the position shown in Fig. 1 any movement ofcrank 6 causes an instant movement to be imparted to the dasher, whilethe movement imparted to the receptacle is not so perceptible at start;but as said crank moves upward the movement of the dasher decreases,while that of the receptacle increases, and vice versa, as the positionof said crank is changed, and at no time is there a stoppage in themovement of both parts so long as motor power is applied.

The protecting-hornsj and 7x3 afford an inexpensive and secure means forretaining the rod H upon its studs when in an operative position, and isreadily removed therefrom, in the manner hereinbefore stated, whendesired to clean the clothes-receptacle or for any other purpose.

The machine as a whole is simple of construction, cheap of manufacture,and durable in operation.

I am aware that it is not new, broadly, to provide means for operatingthe clothes-receptacle and dasher simultaneously from a singlecrankshaft; but

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a washing-machine the combination with an outer casing or tub, aribbed receptacle pivotally mounted in said tub, a top or cover hingedto the tub, and a dasher pivotally mounted in elongated bearings in thetop or cover, of a crank-shaft, a pitman pivotally connecting thecrank-shaft and rubber, and a rod detachably connected at one-end to oneend of the pivoted receptacle, and pivotally connected at its other endto the pitman at a point near the crank-shaft, substantially as setforth.

2. In a washing-machine the combination with an outer casing or tub, aribbed receptacle pivotally mounted in said tub, a cover hinged to thetub, brackets secured to the inner faces of the sides of the cover andhaving closed elongated grooves and a rubber having bearings which restwithin said elongated grooves, of a crank-shaft journaled in bearingscarried by the cover, a pitman connecting the crank-shaft and rubber anda rod detachably connected at one end to one end of the receptacle anddetachably connected at its other end to the pitman at a point near thecrank-shaft.

3. In a washing-1nachine, the combination with a tub or casing, a coverhinged thereto, a receptacle pivotally mounted in the tub, and a rubberpivotally mounted in bearings carried by the cover, of a crank-shaft, apitman connecting thecrank and rubber, plates each having a stud and ahorn each latter being in a plane adjacent to the free end of its studs,one of said plates being secured to the receptacle and the other to thepitman and a rod mounted at its ends on said studs and retained againstaccidental displacement by the horns, substantially as set forth.
